Clear heat (Qing Re)

Clear heat (Qing Re) is a fundamental therapeutic principle in Traditional Chinese Medicine (TCM) rather than a specific molecular target, receptor, or enzyme. It refers to a category of medicinal substances and treatments used to neutralize 'heat' syndromes, which in modern clinical terms often correspond to states of inflammation, fever, and infection (1.3.2, 1.4.1). While not a single molecule, 'clear heat' herbs such as Scutellaria baicalensis and Coptis chinensis contain bioactive compounds like baicalin and berberine that interact with various modern biological targets, including NF-κB, TNF-α, and various interleukins (1.3.3, 1.3.5). In the context of drug discovery, 'clear heat' serves as a phenotypic starting point for identifying multi-target anti-inflammatory and anti-infective agents (1.3.4, 1.4.2). Consequently, it is considered a therapeutic strategy or pharmacological class rather than a discrete biological entity. Biotech analysts should recognize that while the term lacks molecular specificity, it describes a well-documented set of pharmacological effects aimed at restoring immune homeostasis (1.4.3).
